국내 조종사 자격증명(회전익항공기)은 육상 단발/다발, 수상 단발/다발로 등급이 분류되어 있어 육상 다발 자격증명을 이미 취득한 조종사가 육상단발 헬리콥터 비행을 하기 위해서는 육상 단발 자격증명을 추가로 취득해야 하는 것이 국내 자격증명 제도이다. 이에 본 논문에서는 비행기와는 다른 독특한 헬리콥터 비행특성에 대해 살펴보고 헬리콥터 등급분류인 단발/다발 구분의 필요성에 대해 검토하였다. 또한, 세계 및 국내 민수 헬리콥터 산업의 발전방향과 해외 항공선진국 조종사 자격증명 제도를 비교하여 국내에 적합한 회전익항공기 조종사 자격증명 등급분류에 대한 개선방안을 도출하고자 한다.
